Following Redingensians loss in the national 3 play off, and Chard's win over Towcestrians to earn promotion, there are 15 sides lined up to compete in National 3 SW next year. They are:

Existing Nat 3SW sides:

Redingensians
Bracknell
Newton Abbot
Amersham & Chiltern
Old Redcliffians
Brixham
Barnstaple
Weston-super-Mare
Old Patesians
Old Centralians

Bournemouth - relegated from nat 2 South
Exmouth - relegated from nat 2 South
Hornets - SW 1 West champions
Oxford Harlequins - SW1 East champions
Chard - SW 1 play off winners

As there are 15 sides, one team will need to transfer to the London division, with Amersham or Bracknell most likely.

However, the division will contain 4 Somerset teams, 4 Devon sides and 2 Gloucestershire clubs. A location map of all next year's level 5 clubs can be seen here
